The Ethereum blockchain puts quantum security and privacy first

According to Vitalik Buterin, co-founder of Ethereum, the updated roadmap includes native rollups and privacy enhancements as well as post-quantum scale. This is because advances in AI and cryptography have reshaped long-term network technical priorities.

Vitalik Buterin (ETH) has compared Ethereum’s current Strawmap with its roadmap for 2023 in an X post from 10 August. He identified several technologies which gained, lost or have changed their priority during the past three-year period.

Buterin stated that the plans still overlap in many areas, however the implementation and order of some goals has changed. The roadmap has shifted the focus to quantum security, with verifiable delays functions and other proposed Ethereum Virtual Machine enhancements receiving less attention.

Ethereum researchers also replaced older designs as they identified alternates. Verkle tree plans shifted to a binary unified tree, and then a PBT. State expiration evolved into an broader proposal of new state types.

Buterin says that the biggest differences are in areas which were not included on the roadmap for 2023. The list includes native privacy, scaling after quantum, simplified specifications for formal validation, markets for future gas and blob capacity, native rollsups, and more.

Ethereum quantum privacy and security moves forward

The addition of native privacy to Ethereum is clearly a step in the right direction. Buterin listed keyed privacy pools, FOCIL parts, recent roots, and lean privacy pools as mechanisms currently being investigated.

In the future, keyed-nonces could be used to make it difficult for observers to link a user’s transactions. Meanwhile, recent root mechanisms might allow private apps to check recent blockchain states while not revealing an entire history. FOCIL aims to improve the inclusion of transactions by making them more resistant to block builders’ censorship.

These changes are based on Buterin’s three-step Ethereum privacy plan This proposal was released in May. The proposal was a combination of account abstraction, FOCIL and keyed nuces with changes made at the wallet layer and access layer to reduce metadata leakage.

The post-quantum scaling is also a priority. Ethereum is currently dependent on cryptographic systems which could become vulnerable in the future if powerful quantum computers appear. The scaling issue is how to replace these systems without drastically increasing verification costs or network bandwidth, signature sizes, etc.

LeanSPHINCS Signatures, Signature Aggregation, and “zkzk frames” As potential components of the solution. Crypto.news reported previously that an Ethereum researcher demonstrated account-level post-quantum protection At an estimated cost per account of $0.07, this shows that wallet preparation can begin prior to a protocol upgrade.

Ethereum’s Strawmap has not been finalized. This document is meant to be a coordinated plan for proposed updates through the year 2029. Individual changes will still require research, testing, as well as agreement between developers, before they are implemented on the Ethereum network.

Native rollups enter Ethereum’s design space

Buterin stated that native rollups weren’t included on the roadmap for 2023 because developers were still not ready to integrate them into Ethereum base protocol.

Rollups operate currently as separate layers-2 systems. Rollups are systems that process transactions in a layer outside Ethereum and then submit the proofs of transaction or data back to Ethereum. The rollups each maintain their own contract, proof system and upgrade controls.

Native rollups would bring part of this verification into Ethereum. The base protocol may provide a mechanism that is standardized for checking transitions in state, reducing the need to maintain custom infrastructure.

A change of this kind could be a step towards simplifying the relationship between Ethereum, its layer-2 networks and their networks. However, the precise design has yet to be determined. The developers would need to determine which functions would become native and how virtual machines will be supported. They would also have to consider whether or not protocol level verification would create new complexity.

Ethereum is changing its broader approach to scaling. Buterin explained that Ethereum is no longer trying to scale each type of activity using a generalized mechanism. In lieu, developers can build highly-scalable systems that are more limited for certain use cases like token transfers, exchanges and privacy protocols.

The approach would allow Ethereum to perform specific, high-volume tasks more efficiently. This is without the need for every application or node to have to be able to run in the expanded environment.

The addition of blob and gas derivatives is another concept that was not on the roadmap in 2023. The markets allow for users and layer-2 networks alike to fix future data access or execution capacities, which reduces uncertainty in costs when demand is high.

AI can make Ethereum verification easier

Ethereum’s new roadmap places increased emphasis on the need to simplify protocol specifications so that developers can verify their behavior.

The formal verification process uses mathematical proofs in order to verify that software adheres to its rules. It has traditionally taken a lot of time and required specialist knowledge to apply it to a blockchain protocol, especially when there are multiple clients and cryptographic systems involved.

Buterin claimed that the advances in artificial-intelligence are making large-scale testing more feasible. He previously said AI-assisted formal verification Could become “final form” This allows software developers to create code that is optimized and also has a machine-checkable record of its correct operation.

Ethereum uses STARKs to verify its proofs. Recursive Starks allows one proof to be verified by another and produce compact evidence for increasing large computation batches.

Buterin stated that the same verification technique could be used across Ethereum’s data, execution and consensus layers. But if a proof system is used throughout, the implementation of the protocol will be more secure, and the requirement for independent testing, formal verification, would increase.

Ethereum’s virtual computer may also evolve as new systems are developed. Buterin claimed that zkzk-frames could require the protocol expose an alternative instruction set to the EVM.

According to one model, an EVM can continue to be used by developers for existing applications and could also act as a representation intermediate above a more basic instruction set. Buterin warned that the EVM design is still too young to be included in the Strawmap.

The Roadmap is a plan for long-term coordination

Buterin’s Comparison provides Additional Detail on Ethereum’s proposed Lean rebuild, which seeks to make the protocol quantum-safe, private, censorship-resistant, and easier to verify over the coming years.

This direction may eventually impact U.S. exchanges, wallet providers, institutional stakeholders, and layer-2 operators who rely on Ethereum. Nevertheless, there was no announcement of a software release or hard fork for immediate users.

The research and governance process of Ethereum must be followed for each major proposal. Native rollups and alternative instruction sets are still technical directions, not features that have a fixed date of activation.

EthereumETHThe roadmap update was not met with a positive response. ETH is trading at $1,875 and has fallen 2.6% since the 24 hour period prior to this article. The broader crypto markets have also weakened.

The most recent comparison does show how Ethereum has expanded its development priorities since 2023. The main focus is still scaling, but now privacy, quantum-resistant protocols, and verifyable protocol designs are more important in determining the future of Ethereum.
